Description:
| Overview
The Symbian API contains the helper class CAknIconArray that allows reading icons for the listbox from resources. It uses the AKN_ICON_ARRAY structure. Could you provide an example of how this functionality is used?
Solution
Fill in the resource the following way:
RESOURCE AKN_ICON_ARRAY r_icon_testIcons
{
type = EAknIconArraySimple;
bmpfile = "z:\SYSTEM\DATA\AVKON.MBM";
icons =
{
AKN_ICON
{
iconId = EMbmAvkonQgn_indi_checkbox_on;
maskId = EMbmAvkonQgn_indi_checkbox_on_mask;
},
AKN_ICON
{
IconId = EMbmAvkonQgn_indi_checkbox_off;
maskId = EMbmAvkonQgn_indi_checkbox_off_mask;
}
};
}
This resource contains the default icons for checkboxes.
In the source code, call CAknIconArray::ConstructFromResourceL() to construct the icons.
...
// CAknSingleGraphicStyleListBox* iListbox;
iListbox = new(ELeave)CAknSingleGraphicStyleListBox();
iListbox->SetContainerWindowL(*this);
TResourceReader reader;
CEikonEnv::Static()->CreateResourceReaderLC(reader, R_LIST);
iListbox->ConstructFromResourceL(reader);
// Creates a GUI icon array.
CAknIconArray* icons =new(ELeave) CAknIconArray(2);
CleanupStack::PushL(icons);
icons->ConstructFromResourceL(R_ICON_TESTICONS);
// Sets graphics as ListBox icon.
iListbox->ItemDrawer()->ColumnData()->SetIconArray(icons);
CleanupStack::Pop(); // icons
CleanupStack::PopAndDestroy(); // reader
